Hey guys, I'm a pretty big movie buff, but conversations with various people have led me to believe that the list of moves that I've seen is pretty sad. So What movies would yall say are must sees? I mean like the best of the best.

Things that I have seen that I would put on a list like this:
Avatar
Serenity
Inception
Dark Knight
Bicentennial Man
Fiddler on the Roof
Forrest Gump
Star Wars
Back to the Future
Indiana Jones

These can be any genre; action, romance, comedy, live action, animated, etc, but I probably won't watch horror movies. And if we could keep it to pg-13, I'd appreciate it. I'll make a few exceptions there, but not many.

The Lives of Others
Fight Club
Infernal Affairs (the original Hong Kong film that The Departed was based on.)
Oceans Eleven
The Blues Brothers
Zodiac
Se7en
No Country for Old men
Shaun of the Dead
Pulp Fiction

Well, that was going to be a few of my suggestions. So here are a couple of others.
Kung Fu Hustle
Sin City
Shaun of the Dead
Children of Men
Princess Bride
Army of Darkness
Airplane/Flying High
